This invention pertains to a rug rolling and wrapping machine, and hasprimarily for its object to provide a machine which rapidly andefficiently rolls and wrapsa rug, without the use of a winding barorcore, thus materially facilitating theoperation, with minimum laborand effort on the part of the operator.

Incidental to the foregoing, a more specific object of the inventionresides in the provision of a power-driven machine into which one edgeof a rug is fed and directed into a spiral wind, which, when completedand wrapped, is ejected from the machine by a manually actuatedmechanism.

Another object of the invention resides in the provision of a drivenfloating roller cooperating with a pair of fixed driven rolls, to effectboth rolling and wrapping oi! the rug without the aid of a central coreor pole, such as now employed.

A still further object is the provision of a pressure roll cooperatingwith one of the fixed driven rolls to hold the rug upon the same,together with fingers cooperating with the fixed driven rolls forguiding the leading edge of the rug into a spiral wind, and subsequentlyejecting the rolled a and wrapped rug from the machine.

Lastly, it is an object to provide wipers operatively connected to thefloating roller for automatically tucking the ends of the wrapper.

With the above and other objects in view,which will appear as thedescription'proceeds, the invention resides in the novel construction,combination, and arrangement of parts, substantially as hereinafterdescribed, and more particularly defined by the appended claims, itbeing understood that such' changes in the precise embodiment of theherein disclosed invention may be made as come within the scope of theclaims.

In the accompanying drawings are illustrated one complete example of thephysical embodiment of the present invention constructed according tothe best mode so far devised for the practical application of theprinciples thereof.

Referring now more particularly to the accompanying drawings, thenumeral I indicates generally a fabricated frame consisting of endmembers 2 connected by longitudinal struts 3, which are supported atspaced intervals by suitable legs 4. Spaced intermediate the end members2, and connected to the longitudinal struts 3 are transverse beams 5,which carry fixed driven rolls 6 and 1, respectively, the shaft 8 of theroll I being journaled in bearings 9 mounted on the'crossm Journaled inbrackets 16, carried by a suitable m framework I! connected to a pair ofintermediate legs 4, is a driven shaft l8, provided at one end with adrive pulley l9, which may be driven by a belt from a motor, or othersource of power,

not shown. Mounted on the shaft I8 is a sprock- 25 et 20, alined withsprockets 2| secured to the shafts 8, l0, and I4, all of which areoperatively connected by a link-belt or chain 22, one stretch of. which.receives a floating sprocket or pulley 23,- carried by a shaft 24, theends of which re- 9 ceive weights 25 vertically guided between spaceduprights 26 carried by the frame l'l. Obviously, the floating weightedsprocket 23 serves to retain tension upon the link-belt 22, and alsocompensates for transverse adjustment of the roller h.

Slidably mounted on the end members 2 are brackets 21 for reception ofvertical rack bars 28, provided at their upper ends with bearings 29 inwhich a longitudinal shaft 30, that carries a flanged roller 3| isjournaled. Transverse ad- 4 justment of the brackets 2'! on the endmembers 2 is obtained by jackscrews 44. Inasmuch as it is desirable todrive the floating roller 31, a compensating drive 32 is provided at oneend of the machine, and comprises a pair of pivotally con- 45 andmeshing withthe rack bars 28 to impart vertical movement-to the bars androller 8|, for the purpose hereinafter explained. For rotating the shaft38 and pinions 39, a lever 40 is loosely Journaled on the shaft 38 andprovided with a manually actuated detent 4| for selective engagementwith the teeth of one of the pinions 39. Obviously, when thedetentengages the pinion 39,and the lever d is rotated downwardly,vertical movement will be imparted to the rack bars 28, which causes thefloating rollertl to be raised. At the same time, when the lever 40 isin its normal raised position, and the detent t! is disengaged from thepinion 39, the rack bars are free to move upwardly as the diameter ofthe rolled rug increases during the rolling operation to be laterdescribed.

As best shown in Figure 1, downward movement of the rack bars 28 islimited by fixed collars 42 carried by the rack bars and engaging bosseson the brackets 21. After a rug has been rolled and wrapped ashereinafter explained, and it is desired to remove the rug from themachine, it is necessary to raise the floating roller 3'! sufficientlyto allow the rug to clear the roll, and this is accomplished byactuation of the lever, 40,

' which rotates the pinions 39 in the manner described. In the raisedposition of the roller 3!, the lever til is releasably latched in itslower position indicated in. dotted lines, by a pivotal dog it carriedby the adjacent end member 2.

To hold the rug against the roller 6, particu- I larly during theinitial winding operation, a

longitudinal floating roll t? is mounted above I the roller t, by meansof spaced arms 48 secured upon a shaft ll pivotally connected to theframe 3, as best shown in Figures 2 and 4. To facilitate insertion ofthe leading edge of a rug into the winding rolls, it is desirable toprovide for raising the roller d5 upon completion of each rollingoperation. Therefore, an arm dB is secured to the pivotal shaft lll, andextends into the path of travel of the shaft 30, which carries thefloating roller iii, When the roller Si is raised subsequent tocompletion of the winding operation, the arm 65 is engaged by the shaft3@, which in turn rotates the shaft l? to raise the roller d5.

To assist in initial guiding of the leading edge of a rug into a spiralwind, as shown in Figure 5, a plurality of arcuate fingers d9 aremounted upon 3 a longitudinal shaft 58, pivotally carried by the frame iand projected between the flanges of the rolls 6 and i. In addition toserving as guides for the rug, the fingers 69 are also utilized to ejectthe rug upon completion of the winding and wrapping operations. This isaccomplished by means of a foot pedal 5! pivotally carried by the framel and connected with an arm 52 secured upon the shaft 5%, by a link 53.Obviously, depression of the pedal 58 will rotate the forward ends ofthe fingers d9 upwardly, causing the rolled rug to be forced over therear driven roll l for removal from the machine. If desired, tracks orany other receiver may be provided for the ejected rug.

Immediately prior to completion of the winding operation, wrapping ofthe rug is provided for by inserting the wrapping material, preferablyconsisting of a sheet ofstifi cardboard (a) and an outer covering sheetof paper (72), between the turns of the rug in the manner shown inFigure 5, after which the driven rolls are again put into operation towind the wrapper over the rug. As best indicated in Figures 3 and 4,theends of the wrapper W extend beyond the 'rollsand the,ends of the rugR, and therefore. to complete the wrapping operation, rotary tuckers '1are-sethe rug, and which upon rotation engage the pro-' jected ends ofthe wrapper in a wiping action 7 to tuck the same inwardly against theends of the rug, where they are glued, taped, or otherwise fastened.

From. the foregoing explanation considered in connection with theaccompanying drawings, it will be seen that a. machine has been providedfor both winding and wrapping rugs or strips of pliable material,such'as floor padding, carpets, linoleum, and the like; and due to thefact that the entire operation, including starting, winding, wrapping,and ejection, is accomplished through the operation of themachine, laborand time required. are reduced to a minimum.

In operation, it is merely necessary for the operator to place theleading edge of the rug over the forward roller 6, after which the racks28 are lowered to allow the roller it to engage the driven roll 5, andthe floating roll 3! to mesh with the fixed driven roll l. The machineis then put into operation, and, as best shown in Figure 5, the leadingedge of the rug will be guided from the roller 5 to the roller l by thefingers t9, and thence into contact with the periphery of the floatingroller 35. Due to the fact that the periphery of the rollers l and atare travelling in opposite directions at their meshing point, the

leading edge of the rug is prevented from continuing over the drivenroller 6, the roller 3i serving to deflect the same and force'the edgeinto contact with the rug, resulting in a subsequent spiral wind, asshown in Figure 6.

Upon completion of the winding operationand.

insertion of the wrapper as heretofore explained,

- the further rotation of the rug serves to wind the wrapper over the safter which the following edge of the wrapper is glued to the previousturn to seal and completely house the rug, the ends oi the wrapper beingtucked and secured as heretofore explained. The roller at is then liftedupon actuation of the lever ti, and the wrapper roll is easily ejectedby manipulation of the foot pedal El.

The advantages of the foregoing will be obvious when considered inconnection with conventional methods now in use, in which two operators'are required to place the leading edge of the rug into a slot of awinding core or bar, which must then be inserted into the machine afterseveral turns are made to securely attach the rug to the core. Then,upon completion of the wind, the core must be pulled from the machine,and two operators are required to wrap and tape the ends after the rugis removed from the machine.
